4 years ago i was able to solve this by forcing TLS 1.2:
PS C:\Windows\system32> [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
PS C:\Windows\system32> Install-PackageProvider nuget
Name Version Source Summary
nuget 2.8.5.208 https://onege... NuGet provider for the OneGet meta-package manager

Upgraded from WMF 4.0 to WMF 5.0 on Windows 7 SP1 x64 with .NET 4.6.1 and can't get NuGet/OneGet etc. to work at all. Already tried uninstall of WMF 5.0 and reinstall to no avail. Also tried Set-ExecutionPolicy Bypass--same error.
